Question 1. (25p) A fluid obeys the following equation of state. P(Vb)=RT+(TaP2) a=103m3K/( bar. mol) and b=8105m3/mol a) Derive the equations for the enthalpy change of the fluid. b) Using the equation derived in part (a), calculate the enthalpy change (J/mol) when 450K the fluid is brought to 13 bar and from 5 bar and 350K. Note: The average Cp value corresponding to the ideal state is 33.5J/mol.K to Question 1. (25p) A fluid obeys the following equation of state.
